Superhighways used by a population of up to 6.5 million Indigenous Australians to navigate the continent tens of thousands of years ago have been revealed by new research using sophisticated modelling of past people and landscapes.
The new insights into how people not only survived, but thrived, in harsh environments provide further evidence of the capacity and resilience of the ancestors of Indigenous people, and help paint a picture of large, well-organised groups navigating tough terrain.
The peopling of Sahul the combined mega continent that joined Australia with New Guinea when sea levels were lower than today could have taken as little as 5,000 years as people moved from the far northwest, all the way to Tasmania in the southeast.

We used this digital elevation model to understand what was visible to early travellers. Essentially, from each point in the continent we asked “what can you see from here?” This moving window calculates the largest “viewshed” map ever created. When our virtual travellers move, they reorient based on visible terrain everywhere they go. The figure above shows the prominence of features across the continent as increasingly yellow shades against the blue background.
You can clearly make out features such as the the New Guinea Highlands, the Flinders Ranges in South Australia, the Great Dividing Range in the east, and the Hamersley Range in the Pilbara region of Western Australia.
